those who cannot afford to marry should abstain from what is unlawful until god enriches them by his grace. and free those slaves you possess who wish to buy their freedom after a written undertaking, if you know they have some goodness, and give them out of the riches god has given you. do not force your maids to prostitution if they wish to lead married lives, in order to get the benefits of this world. but if someone forces them, surely god (will forgive them) after their forced helplessness, for he is forgiving and kind.
結婚（の資金）が見つからない者は，アッラーの恩恵により，富むまで自制しなさい。またあなたがたの右手が持つ者の中，（解放の証明）証書を求める者があって，あなたがたがかれらの善良さを認めるならば，その証明を書きなさい。なおアッラーがあなたがたに与えられた資財の一部をかれらに与えなさい。奴隷の娘たちが，貞操を守るよう願うならば，現世の果ない利得を求めて醜業を強制してはならない。かの女らが仮令誰かに強制されたなら，アッラーがやさしく罪を赦し，いたわって下さろう。
